In Part 2 of the Impella Guide series by CicuDevices, we explore how the Impella device estimates left ventricular (LV) pressure and derives cardiac output data in real-time.
This episode explains:
• How the motor current reflects pressure gradients across the pump
• The relationship between pressure difference and LV pressure estimation
• How the system identifies LV end-diastolic pressure (LVEDP)
• Why these estimations are only reliable at P-levels ≥4
• The method used to calculate total cardiac output, native output, and cardiac power output using a pulmonary artery catheter and a derived vascular state formula
• Key limitations of waveform-based estimations during Impella support
This video highlights the clinical reasoning behind console metrics, helping you make more informed decisions in the ICU or cath lab.
